Good product
I bought this product at the recommendation of an REI sales associate who said it would seal my tent's seams and those of an old rain suit's. I had just purchased my tent (a used REI Quarter Dome 3T) at an REI garage sale and its seam tape had become brittle where the floor/wall seams met. The rain fly's seams needed some touchup as well. Followed the instructions and put my son inside to look for leaks as I sprayed it with the garden hose. No leaks so far. I will test it in real conditions at some point. However, it was a bit tricky to "paint" the seams with the bottle virtually right side up. May work slightly better with a small detail paint brush.

Fixing The Old Tent Fly
My old tent fly had taping that was flaking and peeling. REI store employee recommended this product. After removing the old taping I applied this product. The bottle comes easy application brush but I chose a little more control and used a 1/2 " art brush. This dries almost invisible and is not sticky like some seam sealers.
Worked great and no leaks.

saved my high priced gear
I am disappointed with the reviews commenting on how difficult this product is to use, as I did not have these issues. In theory you are buying this product to save your expensive gear, thus you should treat the product that way. Set time aside to read all the instructions and follow them and you will not have a problem. I used this product to get my 7 year old hole-riddled mountain bike saddle bags water tight so I could use them for a kayaking trip and avoid having to buy boat specific gear. I also seam sealed all my water proof type bags and other bags. We got crazy wet but our camping gear stayed dry thanks to this product.
A tip on finding and repairing holes: I went in my bathroom, turned off the lights and stuck my head in the black saddle bags while holding my headlamp outside the bag. I used a post-it-note to cover all the holes, revealed by the light and then put seam sealer in all those places, twice. My bags had over 20 holes. My other waterproof bags, I filled with water to see how badly they leaked, let them dry in the sun then seam sealed as instructed. I let them dry after sealing and filled them with water again to insure they were sealed. I was able to seam seal bags that were not even officially water proof making them so. In short, save some plastic backup garbage bags and this product, I spent zero dollars on kayaking gear, saving me and my boyfriend hundreds of dollars.
I am getting ready to use the gear aid to seam seal an 11 oz 9 ft. hexagon shaped ultralight tarp I just made using an old garage-sale ultralight footprint and rain-fly material from an old tent. This product makes crafting custom gear possible, just take your time, follow the directions and save hundreds of dollars.

Works like it should
This stuff works well. I used it to seal the seam of my tent between the floor and the side wall.
It is thick and you need to take your time to apply it.

Seals, perfectly.
I've used this product, before, and I'm firmly convinced that it's the best sealer on the market. And the amazing part of this is that this sealer is water-based.
Before drying, it will, for example, soak thoroughly through the threads in the seams. It also does a good job in repairing tent floors.
A couple of suggestions;
If you need to work in the solution in an area to permeate an area, then use the brush device. But more often, I've found that a foam applicator to be more effective and it cuts down on the waste. One of those small foam paint brushes will do, very well.
I haven't used it, yet, but this product also comes in a pump-spray bottle and there are some applications for this that I've been thinking about.
Hope this helps.

No noxious fumes to contend with the water based formulation. This product is easy to apply. Be patient and setup a well lit area to apply this on the seams. Be prepared to wait while material dries before moving the fabric to coat other areas. The cap can be twisted up or down to regulate the flow. The

Great stuff for parka
I sealed a leaking stitched seam on a 20 year old REI Gore-tex parka with this -- the parka no longer leaks. I wasn't able to get to the back of the seam because the parka has a sown-in lining so I carefully put it on the outside using a Q-tip. There's a slight discoloration but nothing that looks out of place. It's stood up to a month's use and one washing so far with no problems.

Don't waste a dime on this stuff
The product may be good, but I'll never know because the dispenser makes it impossible to apply it. The only way the dispenser is effective is if you are applying it hold the bottle with the bottom up. Problem is, in most cases the seam requires the opposite orientation. The instructions say "squeeze gently". I spent my time either wondering if I was actually applying anything (you can see the stuff on the seam) or wiping it up off of whatever is below the seam she it ozzed out.

Is this the same formula as the Gear Aid Seam Grip Seam Sealer or is it completely different? If not, how is it different? Thank you.
They are not the same formula. Seam Sure is a water-based urethane seam sealer ideal for waterproofing all types of gear. Seam Grip is urethane-based seam sealer and repair adhesive that can be used for repairing holes and improving traction and abrasion resistance in addition to waterproofing.
